Part Numbering System for G Series When ordering, always specify complete catalog number for G Series.

TNR 9 G 271 K

Varistor Voltage Tolerance: K = ؓ10%

Nominal Varistor Voltage: Expressed in volts. The first two digits are

significant figures, and the third digit indicates the number of zeros

following these figures ( e.g. 270 = 27 V; 271 = 270V ).

Series Name: Indicates Basic Varistor Style.

Nominal Case Diameter: 7 = Ø7mm; 9 = Ø9mm; 12 = Ø12mm;

15 = Ø15mm; 23 = Ø23mm.

TNR: Alpha Prefix for Varistors.
